The invention relat ing corrugated board. 7 y 7 One object of .the invention is to increase the output of the machine by ;,providing means to eggpeditethe setting of the adhesive used to secure thecorru gated and facing sheets together so the single-faced product maybe immediately fedto a'double-facer or otherwise disposed of. i

. Anotherobject of the invention is to provide a machine which is adapted to operate at high speedto produce. a 'waterproofed productin which a hotadhesive, such as s phalt, is used to secure the sheetsltogethen Another object of the'invention is to provide a corrugating machine Withmeans to expedite the setting of different kinds of adhesives used in making. different products,

such, for example, as slllcate of soda and asg phalt. This object is attained primarily by providing means to heat and 'to'cool ahot adhesive, such as asphalt, to unite the corrugated and facing sheet. i

Other objects of'the invention Will appear from the specification; L

ticulairly defined by claims at th con l io hereof. I

A discharge piped is connected to carry the fluid from-the drum.

The inlet pipes e for deliveringfluid into the shoes E and inlet pipe (Z for the drum D are connected. to receive a heating medium such as steam from a supply pipe 20 under control of a valve 21 and are also connected to receive through suitable branch connections 24; a cooling medium, such as b11118, or.

cold water,- orair, from a si pply'pipe 22 under control of a valve 23. In the manufacture adhes ves, such as silidifferent adhesive, such-as asphalt, is used. Inorder toadaptthe machine to ex: pedite the. setting of these dilferentadhesives be operated at a the inner face of the of the corruv iheat transference be-. tween'theshoes andthe sheets to dry or set diui n, Each of the slightly respo isively paperor their. adjustment.

when asphalt'is used to secure the sheets together it sometimes occurs that the asphalt cools before the facing sheet is applied thereto and to adapt the machine to this situation, provision is made so that one of the shoes E may be=lieated, while the others are being cooled so that during the initial portion of the passage of the sheets around the drum D, the asphalt will be heated and thereafter the sheets'will be cooled by the remaining shoes with which the facing. sheet contacts. 1

For this purpose the inletcf for the first of the series of shoes with which the facing sheets contact is connected by a pipe 25 to a' branch 26-which is connected to receive steam from supply pipe 20 under control of a valve 27'and to receive a cooling medium from pipe 22 through a branch pipe 28 under control ofv a valve 29. By vmeans of valves 27 and 29, theshoe may be supplied with a heating medium to soften the asphalt, when desired, be-' fore it passes to the remaining shoes which are then bein'g supplied with a cooling me-' branch pipes 2 f and the branch pipe 25 is; connected to an-inlet e" of one of the shoes by means of a flexible section 30 which leaves the shoes free to move to irregularities in the I The outlet pipes e for the shoes are connected by branches 31 .to acommon-outlet pipe 82.
